LORENZ, OF WEST HARTFORD, CONNECTICUT, ASSIGNOR TO HARTTE'OBD- EMPIRE COMPANY, .OF HARTFORD, CONNECTICUT, A. CORPORATION OF DELAWARE LEna LOADEB Application .filed July 12,

My invention relates to apparatus that is particularly suitable for use in transferring glassware to leers, but is capable of employment in various other relations where it is desired to transfer articles from one point to another.

My invention has for one of its objects the provision of a simplified and improved form of ware handling mechanism.

Another object of my invention is to provide mechanism that is capable of transferring articles from a given point to a-receiving surface, and ofdepositing the articles on the receiving surface in predetermined spaced relation and aligned'in a direction substantially transverse to the line of movement of the ware to the receiving surface.

Another'object of my invention is to pro vide a plurality of transfer mechanisms combined to operate as a unit to transfer articles -to a leer conveyer or other surface without interference with one another.

Some of the forms which my invention may take are shown in the accompanyin drawings wherein Fig. 1 is a side elevationa view of apparatus embodying my invention; .;Fig. 2 is a plan View thereof; Fig.3 is an enlarged vertical sectional view of the apparatus of Fig. 1; Fig. 4 is a view on a still larger scale of tong. mechanism which I employ; Fig. 5 is a view taken onthe line 5-5 of a portion of the ware gripping mechanism shown in Fig. 1; Fig. 7 is a view taken on the line 77 of Fig. 3, but on an enlarged scale; Fig. 8 is an enlarged detailed view of a portion of the apparatus of Fig. 1, looking from the rear side thereof; Fig. 9 is a view taken on the line 9-9 of Fig. 8; Fig. 10 is a view showing a modified form of apparatus wherein the transfer mechanisms form a unitary structure but transfer ware from separate conveyers to a leer; and Fig. 11 is a sectional view showing one of the yielding elements which. I employ in twoof the pull chains. Z I I For convenience of illustration, and referring to Figs. 1 to 9, I have shown my apparatus as arranged for transferring bottles or other ware from a conveyer 15 that delivers 1926. Serial 1%. 121,750.

ware from a glass-blowing machine (not shown) or other source, to a leer conveyer belt 16 by which the ware is carried into a leer 11 for annealing.

Above the adjacent ends of the conveyers 15 and 16, I mount a framework 18 that carries a bracket 19 whichis' provided with bearings 20 and, 21 for a swivelled or oscillatory frame 22.

The frame 22 carries a pair ofdepending arms'23 and 24. A shaft 25 is mounted in the swinging frame 22 and supports cranks 27 and 28, and a sprocket wheel 29. One end of a chain 30 is connected to the sprocket wheel 29 and the chain passes around the sprocket wheel and through a sleeveforming part of bearing 21, from whence it extends around a sprocket wheel 31. V The end of the chain 30 is connected to a piston rod 32 that carries a piston 33 which is disposed in a cylinder 34. A pipe '35 is provided for con-' v.

ducting fluid pressure to the'lower end of cylinder .34, from any suitable source (not 7 shown), to move the piston 33 and cause the chain to be drawn over the sprocket wheels 29 and 31 to rotate them. Fluid pressure may also be supplied to the upper end of the cylinder 34, if desired, to make the return stroke of the piston 33 more rapid and thereby increase the speed of the apparatus.

Referring now more particularly to Figs. 3 and 7, when the chain 30 is operated to rotate the sprocket wheel 29 in a clockwise direction, the crank 21' will be turned to exert an upward pull upon a chain 36 that passes around a sprocket wheel 31 which is secured to a swinging arm 38. The arm 38 has ball bearing support upon a shaft 39 which is mounted in the lower end of the arm 23. The

arm 38 will thus be swung in a clockwise diclamping members 43. The shaft42 is journaled in the outer end of the arm 38 and has a sprocket wheel 44 secured thereto. A

chain- 45 passes around the sprocket 44 and a sprocket wheel 46 that is secured to the fixed shaft 39 so that the wheel 46 will not have rotative movement about its center.

It will be seen that when an upward pull is exerted by the crank 27 upon the chain 36, 5 the arm will be swung in a clockwise direction about its pivot 39, and the sprocket wheel 44, by reason of its connection to the nonrotatable sprocket wheel 46, will be given a planetary movement. In other words, the shaft 42 which carries the sleeve.41 and the tongs 40 will be rotated in a counter-clockwise direction with respect to the arm 38, suflicient to maintain the sleeve 41 in a vertical position and prevent idle swaying movement of the-tongs and a bottle carried thereby, while being moved from one position to another. Movement of the chain 36 is continued until the sprocket wheel 37 has rotated 180 degrees, whereupon the arm 38 will occupy the position indicated in dotted lines in Fig. 3, at which position the tongs 40 will be caused to grasp a bottle, by mechanism "-which will be now described.

The tongs 40 (Figs. 4 and 6) are pivotally supported from a cylinder 48 that is secured to the sleeve 41. A. pin 49 extends through arms 50 and 51 of the tongs 40,'so that movement of one tong about its pivot will cause the other tong to havea corresponding movement. The tongs 40 are normally held in contracted or closed position (Fig. 4) by a spring-pressed lunger 52, the pressure of which can be a justed by: a screw 53' which bears against a compression spring 54 that extends into the plunger 52.

Opening movement of the tongs 50 is effected by a piston 55 to the upper side of which fluid ressure is admitted past a piston rod56 to w idh the piston is connected. A suitable choke valvemay be used, if desired, to control the admission of pressure above the piston 55r The piston rod 56 is normally held its uppermost position by a compression spring 57 (Figsf4 and 6). The extent to which the tongs 50 can close is regulated by means of a screw 57 a which engages the to of the piston rod 56, as shown in Fig. 6.

Fluid pressure for effecting downward movement of-the piston 55 and opening of the tongs 40 is supplied through a pipe 58 (Fig. 7) which leads from any suitable source of pressure (not shown). Fluid pressure from the pipe 58 flows through a conduit 59 in the annular'recess-around a reduced portion 64 of the shaft 42 from whence a port leads into i the sleeve 41, so that theair or other fluid shaft 39 from whence it flows through a ra- J with it a piston 67 that fits'within a cylinder 68. Airpressure is constantly maintained .in the cylinder 68 under the piston 67, and is admitted through a pipe 69. The piston 67 thus serves to cushion the movement of the arm 38. To return the arm 38 from the position indicated by dotted lines in Fig. 3 to that indicated by full lines, the air supply through pipe 35 (Fig 1) is exhausted and the air pressure in the cylinder 68 raises the piston 67 and thereby moves the spropket wheel 37 in a counter-clockwise direction.

The crank 28 (Fig. 1) is connected to a chain 71 thatzpasses around a sprocket wheel 72 which is connected to an arm 73 that corresponds to the arm 38 and carries at its outer end a sprocket wheel 74 which corresponds to the sprocket wheel 44. Thearm 73 carries tongs 75 that are operated in the same manner as the tongs 40. The forward end of the'chain 71. is connected to a iston rod 76 that extends into a cylinder 7 which is similarto the cylinder 68. When the crank 28 is swung ina clockwise direction by movement of thepiston 33, from the position shown in Fig. 1, the arm 73 is swung in a counterclockwise direction to transfer a bottle from the conveyer 15 to the leer conveyer 16, and return movement of the arm 73 is effected by fluid pressure maintained in the cylinder 77 which contains a piston (not shown) that is connected to the piston rod 71. The tongs 75 are maintained in substantially vertical alignment, by means of a chain 79 that passes over a fixed sprocket wheel 80 which corresponds to the sprocket wheel 46 of Fig. 7.

'The admission of fluid pressure to the operating pistons 55 of the tongs 40 is so timed that when the arms 38 and 73 are swung to approximately the positions indicated in full lines in Fig. 3, the piston 55 will be moved downward spreading the tongs 40 against the tension of the spring 54 and releasing the bottle. When the arms are moved to the position corresponding to that indicated by dotted lines in Fig. 3, the said pressure is cut off and the spring 54 contracts the tongs against a bottle so that the bottle may be carried to the leerconveyer.

The point at which the bottles are removed from the conveyer 15 is directly beneath the axis of the swinging frame 22 (Figs. 1 and 3) and the arms 38 and 73 have their axes angularly disposed relative to one another in such manner that when swung rearwardly to pick up aubottle from the conveyer 15 the tongs will be directly beneath the axis of the frame 22, while when swung forwardly they will deposit the bottles at different locations latduring movements thereof.

The leer conveyer 16 ordinarily moves quite slowly and it is desirable to place a maximum number of bottles thereon. For this reason, means are provided for oscillating the arms 38 and 73 transversely of the co veyer 16, so that the arm 38 will deposit bott es across substantially one-half the width of the conveyer 16, and the arm 73wi11 distribute bottles across the remaining-half.

In order to effect this lateral distribution of bottles upon the conveyer 16, the frame 22 is oscillated in a horizontal plane'by means of acam member 83 that is -secured to a shaft 84and has a peripheral slot that engages a I cam roller 85 which is carried by an extension 86 of the frame 22, so that as the cam is rotated the-forward end of the frame 22 will oscillate transversely of the conveyer 16.

The cam member 83 is driven fr ma pinion 87 (Figs. 8 and 9) that is secured to a shaft 88 and meshes with a gear vwheel 89 which in turn has driving engagement with a gear wheel 90. The gear wheel 90 meshes with 'a gear wheel 91 that is secured to the shaft 84 upon which the cam member 83 is mounted.

and is intermittently rotated by a pawl 93 which is secured to a sleeve 94 that carries the sprocket wheel 31 around which the chain 30 passes. When the piston 33 is moved toward the upper end of the cylinder, it effects rotation of the sprocket wheel 31 and. causes the [pawl to rotate the ratchet wheel 92'and the cam member 83. By reason of the gear reduction between the ratchet 92 and the cam member, the movement of the cam member is slight and hencethe frame 22 is swungonly' a sufiicient distance to permit a bottle tobe deposited adjacent to a bottle previously deposited upon the leer conveyer 16. The intermittent movement or indexing of the cam .member 83 is such that during each dwell,

two bottles will be transferred from the receiving position on the conveyer or buck 15 to the leer conveyer 16. This is due to the 'fact that the indexing of the cam isv effected by the pawl and ratchet device 92 to 93 above described, which causes the cam 83 to be movedone step for each complete .cyole of the apparatus during which each arm makes a complete two-way oscillation.

As will be seen from Fig. 2, the cam 83 is designed to cause a step-by-step movement first in one direction transversely of the 'receiving conveyer 16, then in the opposite direction, the steps of the cam 83 being such.

that the dwells occurring during movement in one direction are offset with respect to v the dwells occurring during movemgnt in the opposite direction. Through thls arrangement, bottles are deposited properly upon the slowly moving continuous conveyer, so as to most efficiently occupy the conveyer space. As the cam 83 moves'the carriage in one direction, bottles are deposited in spaced relation across the conveyer, and as it moves the carriage in the opposite direction, other bottles are deposited substantially inthe spaces between the first mentioned bottles. When the chain 30 is returned to the position shown in Fig. 1, the pawl .93 will slide over the tooth of the ratchet 92.

When it is desired to vary the length of stepped movements of the swinging frame 22 I sothat articles of different sizes may be comthe movement of the conveyer 15, so that one of the pairs of tongs will always be in position to pick up a bottle from the conveyer 15 as the ottles arrive, and the tongs will be operated in definite relation to the move- A ratchet wheel 92 is secured to the shaft 88 ment of the pistons in cylinders 34, 68 and 77.

In Fig 10, I have shbwn a modified form of apparatus, for transferring glassware from two conveyers 15a toa leer belt conveyer 16a. In this form of apparatus, the oscillatory arms 38a and 73a, which correspond to the arms 38 and 73 of Fig. 1, are eachjmounted on a separate swinging frame. Arm 38a is mounted on a frame 22a and is oscillated in a vertical plane to carry ware from dne conveyer 15a to the leer belt 16a,

while the arm 73a is mounted on a frame 22b and is oscillated to carry ware from the other belt 15a to the leer conveyer 16a.

The frames 22a and 226 are swung about their vertical pivots, by a cam 83a that engages a roller 85a which is mounted on an extension 86aof the frame 22a, so that the arm 38a will be swung in a horizontal plane, to distribute ware acrosssubstantially onehalf the Width of the conveyer 16a. A link 100 connects the frame extension 86a with an extension '101 of the frame 22b, so that said frame will be oscillated about its vertical pivot, synchronously with the oscillation of the frame'22a The arms 38a and 73a are also swung about horizontal pivots 39a and 396, respectively, in substantially the same manner as are the arms 38 and 73 of Fig. 1. In the present instance, however, a cylinder 34a and its piston effect reciprocatory movement'of a piston rod 32a that is connected to a cross-bar 102 1 whose ends are attached to chains 3011 that correspond to the chain of Fig. 3 and pass around sprocket wheels 29a that operate cranks 27a and 28a, to oscillate the arms 38a and 73a, through mechanism of the same character as that by which the arms 38 and 73 are oscillated.

Referring to Fig. 11, I show details of a yielding device 105 for the chains 36 and 71 of Figs. 1 and 3. The utility of the device arises from the factthat there may be failure of some of the mechanism, such as displacement of one of said chains, and one of the arms 38 or 73 may become held in a position Where the other arm will be brought into contact therewith. The yielding device will permit the crank to continue its movement without damage to the apparatus, when moving in one direction. Vhen the crank and its chain are being moved in the opposite direction by one of the pistons in cylinders 68 or 77, the fluid pressure beneath the piston possesses the requisite elasticity.

- This device 105 is in the form of a cylinder that has acap 106 which serves as a seat for a compression spring 107. A rod 108 extends through the cap 106 and has screwthreaded engagement with a turnbuckle 109 that is connected to one of the chains 36 or 71. The upper end of the rod carries a block 110 that engages the upper end of the spring 107. The cylinder 105 is connected to its chain by a block 111 that is riveted in the cylinder and serves also as a seat for llO'when the spring 107 is expanded.

The turnbuckles 109 provide means for adapting the tongs individually to operate between difi'erentreceiving and discharging levels. Thus, if the turnbuckle 109 shown on Fig. 3 is lengthened, the osition of the outer end of the tong arm 38 ecomes lower when in the full-line position of Fig. 3, and higher when in the opposite dotted-line position. The tongs 40 may be adjusted vertically relative to the arms 38, so as to handle ware of different heights, by loosening the clamping members 43 and sliding the sleeves 41 to the desired position, after which the clamping members 43 are again tightened so asto hold the tongs in the desired adjusted position. In order to reduce the power required for winging the ton arms, these arms may be .ounterbalancedy any suitable means.

In the construction shown, the cranks 27 and 28 occupy.dead-center ositions at their upper and lower limits 0 inovement. In order to set these cranks in motion from their upper position, a chain 112 having a spring section 113 is provided, as shown Figs. 2 and 3. One end of this chain is connected to the frame 22, and the other end is connected to the sprocket 29. The chain 112 is of such length that, when its point of attachment to thefsprocket 29 is uppermost, the cha n is in a horizontal plane to distribute the articles transferred.
